The highly anticipated series People Vs O.J. Simpson got off to a dramatic start last night when O.J. was seen threatening to shoot himself in the head while arguing with Robert Kardashian in Kim Kardashian 's teenage bedroom.

In shocking scenes broadcast in the US, O.J. (played by Cuba Gooding Jr), clutched a gun while close friend Robert tried to calm him down and pleaded with him not to commit suicide in his daughter's room.

The explosive events were based on a real incident that unfolded at the Kardashian's Encino home after the murder of O.J.'s ex-wife Nicole Brown Simpson and her friend Ronald Goldman in 1994.

Following Nicole's funeral O.J. hid out at Robert's home and slept in 13-year-old Kim's bed.

In an eerie twist, the production team filmed the series at the actual home where the lawyer lived with his children - Kim, Kourtney, Khloe and Rob - following his divorce from Kris Jenner and decorated the room to match exactly how it looked at the time.

While Robert Kardashian Snr passed away in 2003, he did mention the alleged suicide attempt in a 20/20 interview with Barbara Walters about the trial in 1996.

Sitting with Barbara in Kim's bedroom he said: "O.J. was sitting right where you are Barbara, and as I walked in the room I saw him looking at pictures of Sydney and Justin (O.J.'s children), they were in his lap.

Simpson was acquitted of murdering his ex-wife and her friend Ron Goldman in a criminal trial in 1995.

Kardashian became famous as one of the defence lawyers who helped acquit the celebrated former athlete.

However, a year later, he lost a civil wrongful death lawsuit brought by Mr Goldman’s family, resulting in him paying £21million in compensation. He is currently serving a jail sentence of up to 33 years for armed robbery - not related to the murder.

Kris Jenner - played by Selma Blair - appeared briefly in the first episode at close friend Nicole's trial.
